(2) the die-cutting quality is good. Rotary die cutting is line contact. Low working pressure, good product forming stability and accurate geometric size.
(3) high die-cutting accuracy. Rotary die-cutting machine is equipped with high-precision registration device and die-cutting phase adjustment device, which can obtain quite high die-cutting accuracy. The positioning accuracy of printing, die cutting and indentation can be improved through the tension control system of web feeding.
(4) Long service life. Rotary die cutter can be ground for 3 times, and it can run100000 revolutions after each grinding, which is much higher than other die cutting methods.
(5) Wide application range. Rotary die-cutting can form a printing die-cutting production line with offset press, gravure press and flexographic press. The fastest-growing packaging and printing materials are film and metal foil, which also brings new opportunities to rotary die-cutting machine.
(6) Save paper. On-line rotary die cutting adopts roller paper feeding mode, and continuous cross typesetting can be carried out without leaving the position of mouth and tail during typesetting, which can save about 6% of paper. For enterprises such as cigarette packaging and printing plants, the cost savings are very considerable. Although the domestic production capacity of rotary die-cutting technology is not high, because the manufacturing of tools is complicated, the import cost is high and the maintenance is inconvenient, which affects the advantages of some production lines, with the improvement of domestic technical level, many domestic die-cutting equipment manufacturers have expanded the production of off-line rotary die-cutting equipment, which is a means for die-cutting equipment manufacturers to further innovate according to the characteristics of many processing procedures after domestic packaging and printing. Shanghai bernal Yahua, Beijing Nanfeng Seiko, Shandong Tancheng New Age Machinery, Shandong Linyi Eiffel Machinery and other manufacturers are all home. Domestic production of off-line rotary die-cutting machine equipment combined with the latest international technology, the accuracy and speed of the equipment have been further improved, so many domestic joint ventures and foreign carton packaging enterprises purchase rotary die-cutting machines from domestic machinery manufacturers.
In addition, the production of 650mm die-cutting tools in China has made rapid progress in recent years, which has solved the problem that the original 13 tools have to be sent abroad for maintenance. Such tools are produced by enterprises in Shenzhen, Shanxi, Zhejiang and other regions. Mr. Chang Jiang believes that with the integration of domestic tobacco industry, the centralization of brands and the integration with international standards, there will be more large quantities of long-version live parts, and rotary die cutting is more suitable for the molding and processing of such live parts, and rotary die cutting will usher in the spring of development.
